Cartography of LNV dim-9 SMEFT: Implications for Radiative Neutrino Masses and
Fabian Esser, Lukáš Gráf, Chandan Hati
We perform a systematic study of lepton-number-violating (LNV) dimension-9 operators in the Standard Model Effective Field Theory (SMEFT) that can mediate neutrinoless double beta…
Keeping It Renormalizable: Minimal Baryogenesis induced Asymmetric Dark Matter
Miguel Escudero, Thomas Hambye, Chandan Hati
Many asymmetric dark matter scenarios have been proposed to date. Among them, perhaps the most motivated ones are those in which the dark matter asymmetry is induced from the baryo…
Long-Lived HNLs via ALP Portal at the LHC
Rebeca Beltrán, Chandan Hati, Martin Hirsch +1
Heavy neutral leptons (HNLs) and axion-like particles (ALPs) are both considered well-motivated candidates for beyond the standard model (BSM) physics. If ALPs with sizable couplin…
Importance of Loop Effects in Probing Lepton Number Violation
Lukáš Gráf, Chandan Hati, Ana Martín-Galán +1
The discovery of the lepton number violation would be a smoking gun signal for physics beyond the Standard Model, and its most sensitive probe is the search for neutrinoless double…
Radiative neutrino masses from dim-7 SMEFT: a simplified multi-scale approach
Kåre Fridell, Lukáš Gráf, Julia Harz +1
Lepton-number-violating interactions occur in the Standard Model Effective Field Theory (SMEFT) at odd dimensions starting from the dimension-5 Weinberg operator. Although the oper…
Impact of Bound State Formation on Baryogenesis
Mathias Becker, Kåre Fridell, Julia Harz +1
The mechanism behind the generation of the baryon asymmetry of the Universe (BAU) is one of the biggest open questions of (astro-)particle physics. Popular mechanisms to generate t…
